Got a bit of a dilemma here,what spark plug long reach or short?just putting the engine back together and thought I'd check the head before bolting down,I was going to use a B7HS so try it and there is still thread left in the head for a long reach plug,so I tried a long reach plug no thread left in the head but you can see thread on the plug,wasp performance recommend a B8ES plug which is a long reach plug but I've read about a short reach plug????confused!!!!

Pretty sure youd need a short reach, especially if you can see a couple threads showing with a long reach.

which ever plug dont show threads in chamber as vespaco says , carbon builds on them an can trash threads on removal . how about a copper washer under a long reach ,should keep threads hidden . maybe wasp are thinkin with a cht ring under plug when they say go long reach . ask where ya got kit from , sip dont recommend a type just "a new plug"as a must .

if yours is a mark1 kit it could be different to that as ya link says "redeveloped " for long reach plug , an memorys telling me mallossi re-did the head profile in upgrade ,or so i was told i think .an it does say "2015" spec, so its making me think its a shorty for the earlier 2014 kits like yours .

Ifyoure threads are showing you may need some copper rings to space out the plug, man
